1. Gain The gain of an amplifier relates to how much it can boost the amplitude of a signal. This parameter is frequently expressed in decibels (dB). Gain is defined as the output amplitude divided by the input amplitude into mathematical terms. 2. Output dynamic range The range between th...
A speaker amplifier, or “amp” for short, is an electronic device that boosts an audio signal’s power to a level that can be heard through speakers or headphones. Some form of a speaker amp is necessary regardless of whether you’re playing music from a turntable, a laptop, or a CD...
An amplifier is an electronic device that increases the voltage,current, or power of asignal. Amplifiers are used inwirelesscommunications and broadcasting, and inaudioequipment of all kinds. They can be categorized as eitherweak-signal amplifiersorpower amplifiers. Types of amplifiers Weak-signal amp...
Anisolation amplifier(also called a unity-gain amplifier) is an op-amp circuit which provides isolation of one part of a circuit from another, so that power is not used, drawn, or wasted in a part of the circuit. This will be explained thoroughly now, because this may, at first, appear...

Of these parameters, noise figure is unique in that it is suitable not only for characterizing the entire system but also the system components such as the pre-amplifier, mixer, and IF amplifier that make up the system. By controlling the noise figure and gain of system components, the ...
Gain is the ratio of output power to input power that determines how much signal boost the amplifier can deliver (in dB). It is often specified for the linear mode of the amplifier (in which the change in output power is proportional to the change in input power) (see Figure 1). If ...
